PREFACE

This standard is compiled pursuant to the “Notice of Issuing the 1998 Formulation andAmendmentPlanforNational Standards onEngineeringConstruction (secondbatch)(Jian Biao [1998] No. 244) of the Ministry of Construction, by the Chinese ResearchInstitute of Building Science with joint efforts of appropriate organizations includingthe Project Construction Quality Supervision Division of the Chinese Building IndustryAssociation.

During compilation of this standard, the compilation group made extensiveinvestigation and study, summed up the practical experience of our country in theconstruction quality acceptance of building engineering, adhered to the guidingideology of \separate acceptance and assessment, strengthen acceptance, improvemeasures and perform in-process control,and widely solicited comments fromappropriate organizations.The draft was reviewed and finalized in October 2000 by theMinistryofConstruction.

This compilation is to combine the codes for construction and acceptance of buildingengineering and the standards for inspection and assessment of engineering quality toform a new system of engineering quality acceptance codes, aiming to unify theacceptance methods,quality standards and procedures.Thisstandard definestheunified guidelines for the compilation of construction acceptance codes for eachdiscipline of building engineering, and the quality standards, contents and proceduresfor unit works. Construction site quality management and quality control requirementsare added for building engineering: The sampling scheme requirement is proposed forthe quality inspection of inspection lots. The standard has defined the division ofsub-unit and sub-portioned works in the construction quality acceptance of buildingengineering, and the witness sampling and sample testing in relation to safety andmajor utilization functions of building engineering. The codes for acceptance ofconstruction quality for each discipline in construction works must be applied incombinationwiththisstandard.This standard will likely be subject to partial revision,the information and content ofwhich will be published in the “\Standardization for Project Construction\magazine.In this standard, articles highlighted in bold letters are mandatory articles, which mustbe executed in a strict manner.In order to improve the quality of this standard,all users of this standard are requestedto pay attention to accumulating data and summing up experience in the course ofexecuting the standard. In case of need for revision and supplement identified, pleasesend your comments and appropriate data to the National Center of Quality Supervisionand Inspection of Building Engineering at the Chinese Research Institute of BuildingScience (address: 30 East Sanhuan Road, Beijing, 100013) for reference in the future2
